On page 17 of the manual it states that a student passes a set of facts by meeting or passing his personal goal
without errors. In our school, 3rd grade, a student's goal was 45 multiplication facts. The student got 54 problems but missed one - 1×2. He got that same problem correct several other times on the paper but missed one and the teacher said he had to try again. What are your thoughts on this? Thanks! We love rocket math!

Dr. Don answers:

Cathy, thanks for asking! And a big thank you for reading the manual!!!

Yes, we do say no errors. But, it is clear that the student knows the fact because he answered it correctly. The error is a "rate induced error" meaning he made it simply because he was going so fast. Research shows that students who "know" something can still make up to 5% rate induced errors. So there are certainly reasons to allow the student some leeway.
I'd lean toward leeway, but it might cause a problem because you are being inconsistent.

Our school uses Rocket Math to supplement Everyday Math. We felt that the students weren't learning the basic facts well enough.

In our building each level has it's own reward. If the child passes the letter, they get to stand on their chair and the class gives them a chair cheer (really, REALLY loud screams, cheers, banging on the desks, what ever makes a loud noise!)

When a child passes addition, they get to stand on their own desk and get their picture taken for the Wall of Fame.Dr. Don says: "How cool is this? And it doesn't cost the teacher anything!"

If you have never used the fun and motivating
Wall Chart, you owe it to yourself to try it out.

Yesterday, I saw a second grade class in Portland, Oregon, out in the rain, having popsicles as their treat for beating their goal arrow. Their teacher told me they beat their goal by TWO WEEKS!! She also assured me it was their choice. Br-r-r-r.

I was recently contacted by staff members of a Montessori school that uses Rocket Math as a self-directed, self-corrected practice center. (I'm not sure how they make themselves repeat the fact three times and go back three problems, but I've never worked in a Montessori school.) Anyway, they wanted all the answers to show on one sheet, so I've added that to the Addition 1s-9s drawer in the basic subscription. Normally when you make answer keys (on colored paper in A-Z packets) for the checkers to use, you DON'T want to give them the test answers as well, so they won't be inclined to complete the tests before time begins. But if you need these for some reason, they are now there. I'm working on the other three operations and they should be available in the next couple of weeks. If you need this or some other thing I can provide, please don't hesitate to call. I love to talk about Rocket Math with the people smart enough to be using it!
